It says if you dont check one of the check boxes is configuration ( i cant remember the exact name) it will prompt for a passenger number? That never happens?
Estimate passengers number ( FSX/P3D only )This option is only relevant to FSX/P3D. In MSFS, the default is to always Estimate the passengers number, because we added Simbrief integration, for a more realisticand precise set of the passenger number.
I was referring to the Tool Tip in the config screen. That is where it says you can enter the number of passengers. Old tool tip from P3d I guess?
